TURPENTINE-HACK.

Specification of Letters Patent.

Patented. Dec. 10, 1907.

Application filed September 17. 1906. Serial No. 334.967.

T 0 all whom it may concern:

Be it known that 1, CHARLES H. DRIVER, a citizen of the United States, residing at Tarpon Springs, in the countyotHillsboro and State of Florida, have invented a new and useful T urpentine-Hack, of which the following is a specification.

This invention relates to meansfor scoring trees, and more particularly to cutting channels in trees for the purpose of securing the turpentine and resinous gums therefrom.

One of the principal objects is toprovide a device of this character, which will form a trough shaped groove in the tree, will permit the ready passage of chips and. is not liable to become gummed or clogged up.

A further and important object is to provide a novel and simple structure having cutters that are readily detachable, so that they may be easily sharpened, when they become dull and replaced with new ones when worn out without the necessity of an entirely new device. A. still further object is to pro vide an implement that has a comparatively great length of cutting edge and to so construct the same that different portions of the edges can be brought into action.

Another object is to provide a hack with a plurality of cutters, which may be employed independently or simultaneously, said outters delivering the chips into a comparatively large passageway through which said chips will easily pass.

The preferred, but not the only embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of the hack, the handle therefor being indicated in dotted lines. Fig. 2 is a rear elevation of the same. Fig. 3 is a sectional view on the line 3-3 of Fig. 2. Fig. 4 is a sectional view on the line 4-4 of Fig. 3. Fig. 5 is a sectional view on the line 55 of Fig. 3.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a holder, designated as a whole by the reference numeral 6, comprises a handle engaging shank 7 having an oil-set anchor lug 8 at one end and oppositely extending longitudinally disposed lianges 9 along its outer edge. The shank 7 tapers toward the end having the lug S and its enlarged end carries an off-set body 10. This body is provided with an open-end passageway 11 therethrough, and at one end the passageway is divided by a web 12. The web thus forms in the front end of the body two circular sockets 13 that are internally threaded.

Tubular cutters 14 have their rear ends 15 exteriorly threaded and screwed into the sockets 13. The cutters project in advance of the body and at one side of the shank 7, their front ends being sharpened to provide continuous circular cutting edges 16.

The device may be used in substantially the ordinarymanner, and it will be evident that the chips produced by the cutters after passing through said cutters, enter the enlarged channel 11 and pass freely therethrough and out of the rear end of the body. There is thus no danger of the tool becoming choked or clogged. The cutters can, of course, be readily removed for the purpose of sharpening them, and should one become worn out or injured. from any cause, it may be replaced with a new one, thus avoiding the necessity of an entirely new device. Furthermore, there are distinct advantages for the circular cutters and their manner of attachment to the body. By rotating them, different portions of the edges may be brought into operation, and thus when one portion becomes worn, by slightly turning the cutter in the holder, a new and sharp portion can be brought into operation. While in the present embodiment, two outters are disclosed, it will be evident that the invention is not limited to this number, and that one or more may be employed as desired.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described inventionwill be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a turpentine hack, the combination with a holder, of means for securing the holder against movement to a handle, and a cutter rotatably mounted in the holder to present different cutting edges to the work.

2. In a turpentine hack, the combination with a holder, of means for securing the holder fixedly to a handle, and a tubular cutter mounted in the holder and having a continuous cutting edge at one end.

3. In a turpentine hack, the combination with a holder having, an opening therethrough, of a cutter exteriorly threaded and screwed into the opening of the holder, said cutter having a passageway for the chips.

4. In a turpentine hack, the combination with a holder having a passageway therethrough, of a tubular cutter having its rear portion exteriorly threaded and screwed into the passageway of the holder, said cutter having its front portion provided with a cutting edge and having a chip passageway.

5. In a turpentine hack, the combination with a holder having a passageway therethrough, of means for fixing the holder to a handle, a tubular cutter detachably fitted in the passageway and terminating short of the rear end thereof, said cutter having a continuous cutting edge and having a passageway therethrough that communicates with the passageway of the holder.

6. In a turpentine hack, the combination with a holder having a passageway therethrough, of a tubular cutter having its rear portion exteriorly threaded and screwed into the front end of the passageway, said cutter having a continuous circular cutting edge on its front end,

7. In a turpentine hack, the combination with a holder, of a plurality of relatively fixed cutters secured against movement on the holder and having cutting edges projecting in the same direction.

8. In a device of the character set forth, the combination with a holder having a passageway therethrough, of a plurality of cutters mounted on the holder and delivering chips into said passageway.

9. In a device of the character set forth, the combination with a holder having a passageway therethrou h, and a web dividing the front portion 0 the passageway, of a plurality of cutters detachably mounted in the front portion of the passageway, said outters engaging and being disposed on opposite sides of the web.

10. In a device of the character set forth, the combination with a holder comprising a handle engaging shank, a body provided with an open ended passageway therethrough, and a web dividin the front portion of the passageway and orming circular sockets therein, of tubular cutters threaded into said sockets, said cutters rojecting beyond the front end. of the body and having circular cutting ed es.

11. In a turpentme hack, the combination with a holder, of means carried by one side of the holder for securing it to a handle, said holder having a passageway disposed at one side of the securing means, and a tubular cutter engaged in the passageway and having a continuous cutting edge on its front end.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

CHARLES H. DRIVER.
